忘记mysql密码解决方法

常常忘记root虽然不是习惯，可是不免，因此修改root密码仍是颇有必要的。

1．修改MySQL的登陆设置：

vi /etc/mysql/my.cnf

在[mysqld]的段中加上一句：skip-grant-tables 例如： [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables 保存而且退出vi。 3．从新启动mysql

/etc/init.d/mysql restart

Stopping MySQL: [ OK ] Starting MySQL: [ OK ] 4．登陆并修改MySQL的root密码

/usr/bin/mysql

Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 to server version: 3.23.56 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> USE mysql ; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> UPDATE user SET Password = password ( 'new-password' ) WHERE User = 'root' ; Query OK, 0 rows affected (0.00 sec) Rows matched: 2 Changed: 0 Warnings: 0 mysql> flush privileges ; Query OK, 0 rows affected (0.01 sec) mysql> quit Bye 5．将MySQL的登陆设置修改回来

vi /etc/my.cnf

将刚才在[mysqld]的段中加上的skip-grant-tables删除 保存而且退出vi。 6．从新启动mysqld

/etc/init.d/mysqld restart

Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
